Time to turn out some of the stale winter air in the apartment.
As I've mentioned several times, this is an unusually mild winter, as is often the case during El Nino years in the PNW. But even for an El Nino year, this one has been warm. How warm? Well, as is my wont, I took a stroll around today and took pictures of spring flowers. I'm a little stunned.















(Followup, 2/17: Celina tells me this is wisteria. I'm glad to finally connect the name to the plant; I've heard the name countless times, but not known what it was.)





So is this due to climate change? No. It's due to a somewhat predictable stretch of abnormally warm weather. The east coast has been hammered by an abnormally snowy winter, and I haven't felt that there has been any reasonable amount of attention paid to the fact that the PNW has been balmy to the point of bizarre. I expect the simple reason is that this hasn't caused suffering and disruption, as has the cold snowy weather in the east. But while the planet as a whole may be a bit warmer or colder from one year to another, my sense is that at any given time abnormally cold in one place is balanced against abnormally warm in another.
What climate involves is looking at long term trends. The idiocy of "It's cold, therefore global warming is a hoax," boggles my mind.
There have been a number of fine articles on this topic in the last day or two. One example is "The Dunning-Kruger Effect and the Climate Debate," at Skeptical Science.
The author skillfully dissects a comment left by a reader who tries to make the case that global warming is a hoax, since the Mauna Loa CO2 measurements are often taken as a proxy for global CO2 levels, the peak is volcanic and emits CO2, therefore the data are skewed upwards. The whole thing is worth reading.One of the best titles for a scientific paper has to be the Ig Nobel prize winning "Unskilled and unaware of it: How difficulties in recognizing one's own incompetence lead to inflated self-assessments". The paper compares people's skill levels to their own assessment of their abilities. In hindsight, the result seems self-evident. Unskilled people lack the skill to rate their own level of competence. This leads to the unfortunate result that unskilled people rate themselves higher than more competent people. The phenonemon is known as the Dunning-Kruger effect, named after the paper's authors, and is often seen in the climate debate. There are many with a cursory understanding who believe they're discovered fundamental flaws in climate science that have somehow been overlooked or ignored by climate scientists. Some take this a step further and believe they're being deceived.
Before anyone takes offense, let me begin with some disclaimers. I'm not saying the Dunning-Kruger effect is limited to one side of the debate. It's a universal human condition not confined to a particular ideology. When I first got into climate science discussions, I made my fair share of over-confident yet naive statements. As my understanding grew, I came to realise the complexities of climate science and how much more I have to learn (as predicted by Dunning and Kruger). I'm also not saying all skeptic arguments are a result of the Dunning-Kruger effect. However, a few examples demonstrate how the Dunning-Kruger effect can lead one astray.
I have taken enough classes in atmospheric science to comprehend how gawd-awfully complex it is, and avoid getting entangled in any substantive discussions on the topic. That doesn't stop me from puncturing obvious gasbags, though. And it gives me yet another excuse to gloat over the beautiful climate that I inhabit.
